船用柴油机及内燃机车曲轴的磁粉探伤

Flaw detection for crank shafts on marine diesel and combustion engine with magnetic partides

用磁粉探伤方法对修复中的船用柴油机曲轴和内燃机车曲轴进行无损检测 ,就检测结果作了分析 ,着重陈述了烧瓦裂纹和疲劳裂纹的种类及形貌 ,并提出了裂纹早期预防的几项措施。

Non-destructive testing for the crankshafts on marine diesel and combustion engine used magnetic particles is a good way.This paper tells mainly the category and the form of burned crack and fatigue crack,and proposes several methods to prevent primitive cracks just based on the results of testing analysis.
